降圧・昇圧レギュレータ

STの単一インダクタ同期降圧・昇圧コンバータは、最大3Aの動作電流に対応し、基板面積の削減と電力損失の低減に貢献する4つの低オン抵抗パワーMOSFETを集積しています。リチウムイオン・バッテリで動作するアプリケーションに最適な製品です。

STのバックブースト・レギュレータの主な特徴は以下のとおりです。

  • 主要なバッテリ・ソリューションすべてに対応する広い入力電圧範囲(1.8V~5.5V)
  • 最大3 MHzの高いスイッチング周波数により設計の小型化に貢献(受動部品のサイズが減少)
  • フル・セットのモニタリング機能:同期 / パワーグッド / バッテリ電圧低下検知
  • 軽負荷時の節電モードによる効率向上
  • 通常の効率:>94%
  • 出力電流能力:最大3A
  • 1μA未満のシャットダウン電流によりバッテリ寿命の延長に貢献

これらは、主に入力電圧がVIN - VOUT > VINからVIN - VOUT < VINまで変化できる場合に使用されます。
